200k tune up

Hello everyone, my 2006 Jeep GC Laredo has passed its 200k mark and I really want to keep it running good. As of right now the only things wrong mechanically are the water pump, and I need the starter recall. But other than that, everything runs pretty well at the moment. Since I've owned the Jeep (around 154k) I really have only changed the oil regularly and a couple wheel bearings. That being said I want to do some maintenance and fluid flushes/changes. I want to flush the differentials, transmission fluid and change those.( I am iffy on the transmission fluid change, I've heard it's not always good to do.) Also get new plugs and coils. Anything else someone can recommend doing? And advice will help.
Thanks
-Alex

It sounds like you've covered pretty much everything.

why is a tranny fluid change a bad idea?

Some people feel that at that high mileage, disrupting anything in the tranny could cause a catastrophic failure. Usually they mean the full fluid flush which could possibly knock some crud loose thats actually helping the tranny. I dont see a problem with dropping the pan and changing the filter, then topping it off. But Im kind of leary about the mercedes transmission in my wk as it has no dipstick. I dont want to mess it up. Ive got 190k btw, on my 2008.

Re: 200k tune up

i have a 3.7 2006 model year. im pretty sure i have the merc tranny too. I only have 90k on mine tho. Sometimes the shifts are clean and it clunks in. i dont know why it does it or if its bad. It doesnt bother me but if there is a problem i would like to fix it. I also have never done a transfer case fluid swap, could this be the problem?

Re: 200k tune up

the Mercedes tranny only came on the SRT and the v6. if you have a v8 Laredo you have a 545RFE. if shes running great I would do you basic tune up stuff- seafoam through the brake booster, plugs, I wouldn't swap the coils unless you feel the need it- id go Delphi or OEM. i would have your tranny serviced- do not get a flush- just a simple drain, replace filters and refill. have you had your diffs serviced? tcase?


i have 173k on my 2007, my waterpump was leaking pretty bad at 162k so that's good youre replacing it. id do fluid changes, plugs, just check the other items- belt, brakes, etc. glad to see it made it 200k

Re: 200k tune up

my 2006 has the v6, therefore i have the mercedes tranny. I am not sure if i have the dipstick but ill check tmrw. Im at 92k now and the only work that i have had done is the ignition recall(as a teen I actually turned the jeep off on the highway), ive replaced my front rotors as they were warped and caused a brake pin failure, the waterpump died at 80k which left me stranded and was then replaced, ive put in new shocks and struts, replaced the battery twice, and changed the engine oil religiously.

besides that I have done nothing else. I have owned the car since 2008 and I got it with 12k on the clock.
